PNEUMATIC TIRE.

Specification of Letters Patent.

Patented Feb. 4., rate.

Application filed August a, 1917. Serial No. 184,368.

To all whom it may concern:

Be it known that I, PASQUALE MAKING, a citizen of the United States of America, and a resident of the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Pneumatic Fires, of which the following is a specification.

The'present invention relates generally to pneumatic tires and has for itsmain object the provision of means whereby when a puncture or blow-out occurs, it will not be necessary to remove the whole tire: nor to use tools when inserting a new inner tube into the tire.

The invention consists principally in dividing the shoe in a series of compartments circumterentially with relation to each other and providing each compartment with a flap, or other opening, in its side wall whereby an inner tube section may be introduced independently of other inner tubesections,

' together with means for closing the flap r crete form; and,'as shown and holding it in closed position while, at the same time, permitting the stem of an air valve tofextend through a suitable opening in the side wall of the shoe.

Other features of construction will appear as the specification proceeds.

In the accompanying drawings, I have embodied the invention in a preferred, con- Figure 1 is a sideelevation of a pneumatic tire with parts removed and in section for the purpose of clearness of illustration:

Fig. 2 is a transverse sectional view on the line 22 of Fig. l:

Fig. 3 is a fragmentary sectional view on the. line 3, 3 of Fig. l:'

Fig. 4 is an enlarged detail view showing one of the clamping means utilized:

Fig. 5 is a detail view in section showing one of the split members forming a part of the clamping means: and

Fig. 6 is a detail view of the wing nut constltuting another member of the clamping means. 1 indicates the shoe rim of an automobile wheel and 2 is a shoe having division walls 3 which extend substantially radially with res ect to the center of the wheel and which divide the shoe into a plurality of compartments 4 disposed circumferentially with relation to each other. Formed in the side wall of each of these compartments is a flap 5 which is here shown as an integral part of the shoe and which is provided at its edge with openings 6 that are in the form of a half-circle and that are adapted to be placed in line with corresponding openings 7 in the wall of the compartment when said flap is in its closed position. 8 indicates an inner tube, there being one for each compartment; and this inner tube is provided with an air valve 9 of suitable construction and adapted to extend out to the side wall of the shoe as hereinafter described. This valve is so located as to be in the plane of the corresponding openings 6 and at the middle portion of the flap so that when the inner tube is inserted, through the opening provided by said flap, said valve will, when the flap 1s in its closed position project through the complementary openings 6 and 7. In order to clamp the flap rigidly in position, suitable clamping members are utilized which here take the form of the stems 10 split in two, as shown, and having enlarged heads 11 on their inner sides. It will be apparent that the split members constituting the stem may be inserted before, the flap is closed; and that, when it is closed, it W111 constitute a unitary threaded member with the enlarged heads 11 inside of the shoe. Suitable means, such as wing nuts 12, can then be utilized to hold the split section together and clamp the flap in its closed position. As shown in the drawings, there are three locking members utilized and the central one of these is hollow, as indicated in Fig. 5, to permit valve stem 9 to extend through 1t to the outside of the shoe. The two other clamping members may be solid, as indicated in Fig 3, but, in either event, the split portions will preferably be provided with dowels 13 to insure proper alinement and meeting of the threads.

it is apparent, that should a puncture occur in one of the compartments, it will only be necessary to rotate the wheel a sllght distance so as to bring the deflated portion of the tire out of engagement with the ground. By loosening the locking members and opening the flap, the deflated inner tube section canthen be removed, another one substituted and the flap re-locked in posiltd will

This can be accomplished without jacking the tire up and without the use of remain on the quired, since the rim 1 may eifected.

wheel while repalr is being I claim:

1. A wheel comprising a felly: a shoe having a tread, said shoe being divided into a plurality of compartments, a flap formed in the side wall of each compartment intermediate the felly and tread for the introduction of an inner tube, said wall and flap having complementary openings at their meeting edges, fastening means for securing the flap in pos'tio'n extending through said complementary openings and having means for engaging opposite sides of said flap and wall, an inner tube for each co'mpartment, and an air valve in said inner tube extending through one of the fastening means aforesaid.

2. A wheel comprising afelly: a shoe having a tread, said shoe being divided into compartments circumferentially, a flap formed in the side wall of each compartment intermediate the telly and tread, said side wall and -flap having complementary openings at their meeting edges, an inner extending through said tube for each compartment, split members having an enlarged portion on their inner ends adapted to extend through said complementary openings, and a removable locking member engaging the split-members on the outside of the shoe for holding the flap in position.

3. A wheel comprising a folly: a shoe having a tread, said shoe being divided into compartments circumferentially, a flap formed in the side wall of each compartment intermediate the felly and tread, said side wall and flap having complementary openings at their meeting edges, an inner tube for each compartment, split members having an enlarged portion on their inner ends adapted to extend through said complementary openings and a removable looking member engaging the split members on the outside of the shoe for holding the flap in position, one of said split members being hollow, and avalve on the inner tube hollow member.
